Management of Folliculitis Barbae

Diagnostic Approach

The American Academy of Pediatrics recommends differentiating folliculitis barbae from hidradenitis suppurativa, which causes larger, tender, draining lesions 2
Obtain cultures from pustules or exudate in recurrent or treatment-resistant cases to identify causative organisms, and evaluate for underlying conditions that may predispose to recurrent folliculitis, such as diabetes or immunosuppression 1

For mild cases, apply topical clindamycin 1% solution/gel twice daily for up to 12 weeks, and apply warm compresses to the affected area 3-4 times daily to promote drainage and reduce inflammation 1, 3
For moderate to severe cases, oral tetracyclines (doxycycline 100mg twice daily or minocycline 100mg twice daily) for 2-4 weeks due to their anti-inflammatory and antimicrobial effects, and consider incision and drainage for larger lesions resembling furuncles or carbuncles 1

Use gentle pH-neutral soaps and tepid water for cleansing, pat skin dry after showering, and wear loose-fitting, cotton clothing to reduce friction and moisture 1
Avoid greasy creams in the affected area and manipulation of skin to reduce risk of secondary infection, and counsel patients who shave to use proper lubrication when shaving 2, 3

Implement a 5-day decolonization regimen with intranasal mupirocin twice daily, and daily chlorhexidine washes to reduce recurrences 1
Decontamination of personal items such as towels, sheets, and clothes, and apply mupirocin ointment twice daily in the anterior nares for the first 5 days each month to reduce recurrences by approximately 50% 3
For recurrent furunculosis caused by susceptible S. aureus, consider a single oral daily dose of 150 mg of clindamycin for 3 months 3

Don't continue topical treatments alone when they've already proven ineffective, and avoid using topical steroids on infected areas as they may worsen the condition 1
Don't neglect to culture recurrent or persistent lesions, as this may identify resistant organisms or unusual pathogens, and remember that systemic antibiotics are necessary for widespread folliculitis or cases with systemic symptoms 1, 3
